Clinical application of electromagnetic navigation bronchoscopy-guided localization in elderly patients with multiple pulmonary nodules
Objective To analyze the feasibility of electromagnetic navigation bronchoscopy(ENB)-guided injection of indocyanine green(ICG)to locate multiple pulmonary nodules in elderly patients.Methods From February 2023 to May 2023,7 elderly patients with multiple pulmonary nodules underwent preoperative ENB-guided injection of ICG localization for 15 nodules in Huadong Hospital Affiliated to Fudan University.All nodules were pure ground glass nodules or mixed ground glass nodules.4 nodules were located in the upper lobe of the right lung,3 ones in the lower lobe of the right lung,5 ones in the upper lobe of the left lung,and 3 ones in the lower lobe of the left lung.Results All patients completed ENB-injection of ICG localization under general anesthesia in the operating room.After localization,the patient was immediately turned over to complete single-aperture thoracoscopic resection of pulmonary nodules.The success rate of localization was 93.3% (14/15),and there were no complicationsrelated to magnetic navigation localization.The mean age of patientswas(65.8±4.2)years.The size of nodules was(12.66±3.84)mm,the distance between nodules and visceral pleura was(10.77±6.87)mm,and the average operation time was(18.67±8.74)min.The postoperative pathological results demonstrated that 6 cases were ade-nocarcinoma in situ,6 ones were microinvasive adenocarcinoma and 3 ones were invasive adenocarcinoma.Conclusion ENB-guided injection of ICG localization is an effective and safe method.It can help thoracic surgeons quickly locate multiple pul-monary nodules in elderly patients,save operation time,and is worth of clinical promotion.
